ANALISA OPTIMASI JARINGAN JALAN BERDASAR KEPADATAN LALU LINTAS JALAN RAYA

Abstract

Increasing the population, the number of vehicles,  and activities in Gresik Town causing
social and economic problems that are highly dependent on road transport. These problems arise
because of the imbalance problems such as the high volume of traffic and the increasing number of
people  living  along  the  Gubernur  Suryo  Road.  The  method  used  in  this  research  is  descriptive
study. This method used to look for the amount of capacity and degree of saturation that affect the
activities on this road. Data collection techniques using observation and geometric data. While the
flow of vehicles using MKJI 1997 method. From the effectiveness side, the road capacity is smaller
than planned capacity due to the side barriers and the growth rate of the vehicle in line with the
population increase. From the identification of problems, volumes of traffic is high, amounted 2969
smp/hour. Performance of road being dropped LOS = 1.91 (F), due to the high volume of traffic
that passing through this road is not comparable with the capacity (1548.36 smp/hour) and Degree
of Saturation (DS) greatly affects the traffic flow on Gubernur Suryo Road of = 1.91 smp/hour. The
high  delay  and  side  barrier  amounted  317  smp/hour.  Side  barrier  can  be  resulted  from  the
calculation  of  total  amount  divided  by  the  capacity,  the  result  is  0,20  smp/hour.  It  affects  the
smoothness  of  traffic  flow  because  the  density  of  traffic  and  intersection  of  roads  are  not  well
planned, where the distance of each t-junction is quite far one another. Traffic engineering is used
to solve the traffic jam problems on the Gubernur Suryo Road and along the market road. It is
expected that the government can curb the tricycles parking and vehicles along the road so that
traffic jam can be resolved soon.
